To all whom it may concern skeleton. rolls 11 and 12. The's e rolls are Be it known that ALEXANDER S. SPEER,

a citizen of the United States,

and a residentof the city of Buffalo, county of Erie,

State of New York,; has

rovement in Apparatus invented for Making Roofan Iming Units, of which the following is a specification.

This invention-relates to apparatus for cutting or punchin sheets of material.

. Amongother ob ects the invention is intended to provide improved cutting and.

punching apparatus adapted to eff ciently and rapidly punch clean-cut opening sheet material and to shear the same, if desired,'on sharply defined lines, without distorting or tearing the material punched or cut, and to provide actor particularly shear soft or sticky The invention consists in tions, constructions and arrangements,

The machine is provided with suitable supportingtable 17 for supporting the sheet material. "Intjhe illustrative machine coopcrating pairs off slitting rolls 18 are provided for slitting the sheeti aterial longitudinally.

of the shafts 13, gears I The rolls are separated a suflicient distance to permit'a sheet of material 16 to if desired, they Cooperating pairs ofdie members 19 and asillustrated 'in Fig. 6, these die members I are provided with punches 21 and cooperating open dies 22 spaced apart so as to punch parallel rows of spaced slots23 in the sheet material. The die members are mounted; on the rolls so as to'be capable of movement relative'thereto in order to efiec't'a' proper punching or-shearing action notwithstanding the mounting of the die members on relatively rotating carriers. This may ,be'effected in any suitable manner thepurpose desired. As illustrated, this may be conveniently accomplished by proyiding the lls with a series of bearings 24:

below theperiphery of the rolls, constructed and --arranged to receive the die members andpermit them to oscillatewithin the'bearings. It will be observed that in this construction the punches'21-p'roject'from the.

to accomplish periphery 'o f-th rolls and theloooperating dies 22 arello ated with their; upper surfaces at the periphery of; theroll12. i

' One or both ends of the-die members are provided withlevers thereon. I These rolls ,aresfada 'ted 'to move within cam grooves 21in t eqstationary members 28 secured to'th imme of the machine, opposite theen'd s o'f'therolls'l These rolls during the operations of the dies-on 25' having camj rolls camgro'oves 27 e-so designed torock.

the respective die"meinbersf relative'to' the the punching operation. During this portion of the cycle of movement, the respective pairs of die members travel substantially synchronously with'the sheet and move toward and away from each other .without relative rotation.

The mechanism above described permits the punches 21 to squarely enter the dies 22 and enables the use of dies'22, having only suflicient clearance to effect a proper shear .ing action b the punch. The punches 21 are made su ciently long to permit the use of an adequate shearing angle so as to shear the material in punching with the least ex penditure of energy. The dies 22 are made 25 sheet.-

That part of the cam grooves 27 not actively engaged in rocking the die members during the punching operation maybe of any suitable shape. of circular form in its inactive portion inasmuch as no relative motion of the die members is necessary during this part of the cycle of movement. In fact, this part of the cam groove may be omitted altogether, if desired, provided suitable provisions are made for causing the cam rolls 26 to enter the operating part 31 of the cam groove at the proper time. This may be accomplished by widening the end of the operatmg part 31 of the cam groove in order to insure that the cam rolls 26 will enter the groove at the proper time.

.In order to shear the sheet of material transversely at proper intervals and places, one'or more pairs of die members 19 and20 are provided with cooperating shear members 32 and 33. In the form shown, the shear member 32 is in the form of a blade rojecting from the periphery of the-memer 19 and the shear member 33 is provided with a recess, having an edge adapted to cooperate with the blade 32. As illustrated in ig. 7, the sheet is severed. transversely at every fourth slot. The shear blades are so arranged with respect to the punching dies as to sever the material along staggered lines 34 and 35, extending from opposite ends of the slots 23; This arrangement results in the formation of a conventional,

type of multi-tab shingle, in which one end of the shingle strip 36 projects, as shown at 37, for spacin the strips from an adjacent strip by the wldth of a slot.

The arrangement of .shearin blades may be modified to sever transverse y a sheet acblades.

open, as shown at 29, and the bearings '24- As illustrated, it is cordin to the pattern desired. As in the case 0 the punching dies, during the shearing operation, the shear members do not rotate relatively to each other and, according ly, shear the sheet in a manner corresponding to the action of the stationary shear These shear blades are also made with a suitable shearin angle.

With some classes of material, one set of cooperating dies may be mounted in the roll without capability of relat; "e movement thereto,the die members in ie other roll, however, being mounted so that; during the punching operation or shearing operation, as the case may be, they are rocked or moved relative to the roll so that their rotat n relative to the sheet of material is arresed during the punching or shearing operation. In

shearing or punching material which is soft, relatively thlck, or sticky in character, such as prepared or asphalt roofing, the arrangement illustrated permits the forming of clean-cut slots and sharply defined lines of severance.

It will be observed that, in the illustrative machine, the construction is such that during a single rotation of the rolls, eight strips 36 are formed. It is obvious that the arrangement and shape of dies may be altered to punch or sever different-shapes of material from a sheet. v

If desired, the rolls may be mounted so as not to draw the sheet of material between them. In such a'case, other suitable means may be provided for feeding the material.

The rolls are made of skeleton form so that the punchings or other waste material may fall through the rolls and may be prevented from mingling with the finished product.

Obviously the invention is not limited to any particular form of construction andthe details of the illustrative apparatus may be variously modified. Moreover it is not indispensable that all of the features of the invention be used conjointly. as they may be used to advanta e in various different combinations and $11 combinations.
